1. won’t turn on
If your iPhone won’t turn on after coming into contact with water, it can be one of two things; either the phone has short-circuited, or the water has damaged or corroded some internal components and compromised the circuitry. Both can be irreversible if the phone isn’t looked at by a technician.
There are a couple of tests you can do to check if your phone actually won’t turn on, or if there is another issue.
2. won’t charge
If your phone won’t charge after dropping it in water, there is probably a problem with your charging port, especially if that was the main place that water entered the phone. The charging port is one of the few places that has exposed electrical components, so there is a lot of potential for corrosion.
The first thing you should do to make sure you don’t damage your iPhone charging port further is to make sure the charging port is completely dry before you plug your phone in. Plugging your phone in when there is water in the charging port will definitely lead to corrosion or a short circuit.
3. screen is water damaged
You can tell if your screen has been damaged by water if there are lines or dark spots under the glass. It is difficult to say whether this damage is going to be permanent or if it will lead to other complications, so the best thing to do is turn it off and leave it to dry for as long as possible.
However, there is no guarantee that circuitry under the water damaged screen isn’t going to corrode over time, and the screen will stop working.
4. speaker doesn’t work
It is difficult to determine whether your speaker has been compromised by water because there are often bigger issues that will stop you from noticing. As with every water-related issue, leave your phone to dry for as long as possible. If you manage to turn your phone back on again, backup your data before you try to test the speaker out.
If there is water in your speaker, using it could cause the phone to short. If you’ve turned your Phone back on after letting it dry for as long as you can, try and play a ringtone or some music through your speaker. This will allow you to identify if there is an issue, however, it should be one of the last things to check in order to avoid your phone shorting and causing more damage.
